Bev it known that'I, DUDLEY E. JONES, a1 citizen ofthe United States, anda resident of No. seeooi.'

' [-Milcfn-l'uls.-BELTI'IMGV.`

Little Rock, in the county of -Pulaski and State ofArkansas, have made a certain new and useful Invention in Machine-Belting;

and I declare the following to be a full, clear,Y

' 4and-exact description ofthe same, such as will enable others skilled in the art to which it appertains to make and'use the invention,

"reference being had tothe accompanyin bs's ' i soli appearance. The lines of stitching are,

drawings, and to letters of reference marke ythe'reon,'which form-a part of this specification. i

- Figure 1 is aplan view of a section of four-y ply belting embodying -my invention. Fig. 2 isa` longitudinal section of aportion ofmy belt. Fig. 3 is a view similarl to Fig.v 1 of a section of three-plyfb'elting. Fig. 4 is a longitudinal section of the same. The invention relates to belting which is made in layers of canvas or other stout tex'4 tile material; and it consists :in .a device .whereby the number of layers of lwhich the 25 belting is composed; is indicated in a continui ous manner(A throughout .the length'of the` belting.`

. Belting of pliesv of -t e canvas fastened together. by-

rows of stitching and finis ed by treatment with pigment, 'and com ressionin -such na mannerthat it'becomes 'or all practical lpurposes a single band admirably'ada ted to the pur oses of machine-belting an having' a` however, Asuperficially a parentbecause of ltheirstrong `threadan l:indicate that the It is imbelting is made' of layers of'canvas. portantthat `the number 'of layers or plies of -which a piece fof such belting 1scomposed shall be plainly indicated in'y order' that its exact strength maybe readilyl known, and e this is a matterI which in ordina canvas belting can ,only belascertained wit consid- I n erable diiicul'ty by cuttinginto the belting and separating the plies, andV thus injuring a portion of\it The *ordina marking on a part or end of the pieceof be ting'maybe'def specincation of Letters Patent; .i 'Applinion @hummm 21.1905.v semi No. 293.848.

, the `character tolwhich this i`ni vention applies consistsof several layers or 3 .means of continuous lon tudinal parallel 1 bei widt than those between the rows of stitch?` Patented 18,1906. A

i lfaced"orthe'ma'rked art may have beenhcut off, leaving no clue o positive nature.

such grou s being parallel and consisting eac z v My device consists in providing the belting i with groups of rows of continuous stitchi of a num er of equidistant rows of stitching' layers in .the belt. separated from each other y'intervals which are wider or narrower than the intervals between the rows of' stitching of eachvof such from the number `of rows in a group how many layers or plies there are in'the belting.

In a-three-vply belt the groups will consist of three rows/of stitching equally separatedfrom eachother, said groups being se arated kwhich is the same .as the number of plies or .The ply-mark' groups are groups, so that any one can tell ata glance V,

by wider or narrower intervals than t ose between the rows cfa group.

In the drawingsthe etter a indicates a piece of ,four-'ply belting, having four row groups b, separated by intervals c, and d represents apiece of threely belting,`whos'e groups e'consist'each of t ee rows of stitch.

This

ing, and so on to any number of plies.

ply-markfextending throughout the length `of the belting and formed by a necessary element'f its construction, is available in'every portion of the band on bothsides and a itvdoes not addto the expense of manufacture nor 'injure the belt is designed to serve the-purn'poses of such a mark in a very convenient and effective manner.

of stitching of the same number, such groups ,separated byintervals of different ing; but it is evident' that the number ofv lies may be indicated in a singlerowfof stitcliing by separating the stitches of such row into' It is 'preferred to indicate the'number-"of :plies by means oflongitudinal groups of rows groupsof two, three, or more stitches, as the casemaybe. ,y Y
